Be it known that I, HARR E.- 1901mm, a

citizen of the United States, residing at St.

Louis, Missouri, have invented a certain new and useful Improvement inFour Wheel Trucks, of which the following is a full,

clear, and exact description, such as will enable others skilled intheart to which it.

ap ertains .to rnake and use the same.

' vertical longitudinal sectional view taken on the line 2-,2of Fig. 1;Fig.3 is a vertical cross sectional view taken on the line 3--3 of Fig;1; Fig. 4 is an end elevation and ver-' tical cross sectional view'takenon the line 4-4 of Fig. 1; and Fig. 5 is a detail sectional viewtaken'on the line 5-5 of Fig. 1..

Referring to the drawings which illustrate the preferred forni of 'myinvention, A designates aoneiececasting which cornprises a pair of wreel-pieces 1, and two smgle transorns 2 that connect said wheel-piecestogether. The wheel-pieces lare preferably channel-shaped ih-crosssection andare'arranged with. their horizontal flanges a pro:- jectingoutwardly,.as shown in-Fig, 3. The

pedestals Bof the truck are'removable, and

at the points where the are detachably con: nected to the wheel-p eces1, said wheel pieces are '[provided with short outside verthatareintegrally connected to;

tica-l webs v the horizontal flanges 12, thus produc ng boxshapedportions which are embraced by the uppe r'ends of the pedestals B andthrough which the fastening devices 3 pass, asshown" in Fig. 4. Byforming the wheel-piez'ms;inv

this manner I obtain an exceptionally strong and rigidetruck frame forthe short webs ,b

' .reinforce those portions of the wheel-pieces 1 which are subjec ed togreat strains, and they also brace thei) ing devices which secure thepedestals to the wheel-pieces. p

The wheel-p fcs 1 are rovided on'tneir under sides with integraspringrseatsj o'r pockets 4 which receive the uppefends Specification oiLetters Patent. Application filed September so,- 1911. Srla'lJo. 652,04.

of a four-wheel edestals'and the fasteriof the spring that areinterposed between the wheel-pieces and the equalizers D. Said springseatfs tare of greater diameter than the w1dth.of the horizontal flangesa of the wheel-pieces and consequently projec.t-later-' ally oppositedirections fromisaid wheelpiecesgas shown lnFig. 3. Th'poitiOns ofPatented Jan.16,1 912.

said springfseats which project outwardly from the wheel-pieces arereinforced and strengthened by vertical ribs 5 which-arexintegrally"connected to the spring seats and to the vertical andhorizontal flanges of'the wheel-pieces 41, and the portions of saidspring' seats1\\'hich project inwardly from the wheel-pieces arereinforced and stren'gtlr ened by the transoms 2 to, which they arentegrally connected,- as showni-in -F1 The transoms 2 are so deslgned-an ar ranged that the truck ispractieally a'sstrongon-eaeh side of thebolster, therebyredueing the weight ofthe truck-and'the cost ofrnanas'a' truck provided with 'double -transoms lufacturmg same." Saidtranso'ms 2 are 10 cated'some distance 'awayfrom the bolster E,preferablyabout midwav between I the holsteran'd the-wheel axles as;shown in Fig. Land each transom consists-of a relatively narrow,intermedlate or central portion and two relativelynwide endportion's"that'cotiperate with the end-portions of the other transom to guide theholster and pre vent it fromswaying. The transoms' 2 aresubstantiallychannel shaped in cross section and comprise top and bottomflanges that trans'oms and wheel-pieces.
